Stax decks typically have broad effects, such as preventing players from tapping lands for mana or forcing players to sacrifice their creatures
Sometimes, sideboarding can be the most important factor in determining how two decks will match up against one another
The Black White Rare cards specifically caught my attention, although I didn't pull Reshiram, Zekrom or Victini
Then theyve added the shadows and made some other small changes, so the fourth, fifth, sixth, and seventh print runs were unlimited edition, and these four print runs dont have any differences as far as anyone could tell (I have heard some rumors about some semi-glossy unlimited edition Base Set cards however, which Im still investigating - although those seem to be regional differences instead of print run differences)
After years of collecting, Ive learned exactly what separates the valuable pulls from the bulk commons
